This application claims the benefit of U.S. Patent Application Ser. No. 62/823,225, entitled “AUDIO SYSTEM,” filed Mar. 25, 2019.
The present invention generally relates to an audio system upgrading a previously existing wired audio system.
Speaker technology has consistently attempted to reproduce a recorded sound in the most realistic manner. The majority of speaker designs employ a variety of sound drivers mounted within an acoustic box. The sound drivers are then connected to an audio source via wires that supply the sound drivers with both power and audio signals. Such arrangements are static and not amenable two variations as the needs of the user change, as the speakers are moved, or as different audio sources and technologies are developed.
As technology advances, the ability to transmit sound information from location to location has similarly advanced. As such, a need exists for audio systems allowing for the interconnection of audio sources and speakers in a flexible, efficient, and acoustically optimized manner.
According to a first aspect of the invention there may be provided an audio system including an audio/video receiver, a power supply/wireless audio distribution assembly connected to the audio/video receiver, speaker wire, and speakers compatible with the power supply/wireless audio distribution assembly.
In some embodiments the audio/video receiver includes audio processing technology.
In some embodiments the audio processing technology is Dolby ATMOS audio processing technology.
In some embodiments the power supply/wireless audio distribution assembly includes an AC input adapted for connection to a power source and multiple outputs adapted for connection to the speaker wire so as to connect each of the speakers to a power source.
In some embodiments no audio signals are sent through the speaker wire and the speaker wire is solely used as a means for transmitting power to each of the speakers.
In some embodiments the power supply/wireless audio distribution assembly includes a wireless transmitter for transmitting audio signals to each of the speakers.
In some embodiments each of the speakers include at least one amplifier and at least one receiver.
In some embodiments the at least one receiver of each of the speakers is a Bluetooth receiver and the wireless transmitter is a Bluetooth transmitter.
In some embodiments each of the speakers is an active speaker or speaker array.
In some embodiments the audio system includes a speaker assembly of which the speakers form a part thereof.
In some embodiments the speaker assembly includes a central support member to which the speakers are secured in a manner allowing for articulation of the speakers relative to each other.
Additional advantages of the invention will be set forth in part in the description which follows, and in part will be understood from the description, or may be learned by practice of the invention. The advantages will be realized and attained by means of the elements and combinations particularly pointed out in the appended claims.
The detailed embodiment of the present invention is disclosed herein. It should be understood, however, that the disclosed embodiment is merely exemplary of the invention, which may be embodied in various forms. Therefore, the details disclosed herein are not to be interpreted as limiting, but merely as a basis for teaching one skilled in the art how to make and/or use the invention.
With reference to
The present audio system 10 has been developed to specifically allow users to take advantage of DOLBY ATMOS technology without the need for complete rewiring of their previously existing audio/video systems. While the present invention is described for use in conjunction with DOLBY ATMOS technology, it is appreciated the present invention may be used in conjunction with various other sound processing technologies, including but not limited to, DTS-X or similar full 3-D audio. As those skilled in the art will appreciate, DOLBY ATMOS is the tradename for a sound processing technology that provides for greatly enhanced surround sound. DOLBY ATMOS allows for the controlled distribution of up to 128 discrete audio elements within a room to create a highly immersive audio/video environment. While DOLBY ATMOS allows for assignment of traditional audio tracks to specific audio channels (for example, left/right channel, rear channel, center channel, etc.), DOLBY ATMOS also enables multiple audio objects to be precisely defined and expressly positioned within the three-dimensional sound field.
Given the capability of DOLBY ATMOS (and similar 3-D audio processing technologies) to create extremely realistic three-dimensional sound environments, these kinds of audio systems are designed to work best utilizing a greater number of speakers than traditional/conventional DOLBY DIGITAL 5.1 or 7.1 speaker configurations require. This may necessitate the use of a combination of down-firing speakers, up-firing speakers, and other strategically positioned speakers to create the desired 3-dimensional audio environment. In so doing, the vast potential number of individual audio “objects/entities” may be accurately reproduced to create the visceral, textured and immersive audio experience associated with a movie, video game or other audio/video content. Within these new 3-D audio technologies, audio mixing engineers enjoy complete freedom to individually select specific placement and movement for each sound within the audio/video content's three-dimensional sound field. Once the audio objects and their relative locations and movements are designated by the audio mixing engineers, this data is captured and encoded into the A/V media. This data will be subsequently decoded by a DOLBY ATMOS (or similar 3D audio) equipped A/V receiver, Television, Media Device or Computer rendering the audio objects in real-time, such that each sound in the movie, video game or other audio/video content appears to be coming from a specific spatial position within the 3-dimensional sound field. Audio objects/entities may move not merely left to right or front to back, but, with these new types of surround sound technologies, distinct sounds may also move discreetly up or down to any point within the defined 3-D aural space.
The present invention takes advantage of the ability of three-dimensional audio processing to create such a sound environment by allowing users to upgrade their preexisting audio/video system with speakers and audio transmission capable of reproducing sound in accordance with protocols defined by DOLBY ATMOS or other state-of-the-art three-dimensional audio encoding/decoding systems.
As briefly mentioned above, the audio system 10 includes an audio/video receiver 14 containing DOLBY ATMOS (or similar) audio processing technology. The audio/video receiver 14 is, therefore, able to process encoded information from an audio/video source and output appropriate audio signals to various speakers within a room. In order to transmit the DOLBY ATMOS audio information being decoded by the audio/video receiver 14 to the speakers 18, 20, 102, 104 in a controlled and effective manner, the audio/video receiver 14 is connected to the power and audio transmission assembly 16. While some channels of audio can still be outputted from the conventional amplifier-to-speaker connections, doing so will be redundant in the main listening environment, while still potentially useful for secondary listening environments, i.e. other rooms or outdoor listening areas.
The power supply/wireless audio distribution assembly 16 serves two functions. First, the AC input 16ac of the power supply/wireless audio distribution assembly 16 is connected to a 100-240 AC/mains power source (for example, electricity coming from the audio/video receiver 14) and the multiple outputs 16o of the power supply/wireless audio distribution assembly 16 are connected to previously existing speaker wires 12 so as to connect each of the speakers 18, 20, 102, 104 in accordance with the present invention to a power source. That is, the power supply/wireless audio distribution assembly 16 is directly connected to the speakers 18, 20, 102, 104 and transmits 12-28 V DC through each pair of speaker wires 12 to the speakers 18, 20, 102, 104 connected thereto. In contrast to a typical arrangement, no audio signals are sent through the speaker wire 12 and the speaker wire 12 is solely used as a means for transmitting low-voltage (Class II) DC power to the wireless receiver/preamp/power amplifier co-located with each speaker 18, 20, 102, 104 connected thereto.
In addition to functioning as a power source, the power supply/wireless audio distribution assembly 16 also wirelessly transmits the decoded audio signals to each of the speakers comprising the audio system 10. The wireless transmission is preferably achieved via Bluetooth technology (as described below in the disclosed embodiment) or multi-channel, high-bandwidth capable WiFi technology, although it is appreciated other known wireless data transmission protocols may be used without departing from the spirit of the present invention.
The power supply/wireless audio distribution assembly 16 is preferably connected to the audio/video receiver 14 in a manner allowing for both the transmission of power thereto and the transmission of audio information from the audio/video receiver 14 to the power supply/wireless audio distribution assembly 16. The audio transmission includes all information necessary to control the speakers 18, 20, 102, 104 in a manner rendering sound in accordance with the DOLBY ATMOS (or similar audio encode/decode technology) protocols/criteria. It should be appreciated that the power supply/wireless audio distribution assembly 16 does not contain the 3-D audio decoding processor, but takes the already decoded audio signals from the audio/video receiver 14 and wirelessly transmits the audio signals to the designated speakers comprising the 3-D audio listening environment. Once the audio information is received by the power supply/wireless audio distribution assembly 16, said assembly 16 converts the collective audio input and wirelessly transmits designated audio signals to the associated speakers comprising the audio system 10 via multiple Bluetooth transmitters 24 located within the power supply/wireless audio distribution assembly 16.
The speakers 18, 20, 102, 104 of the present audio system 10 are active speakers/speaker arrays specifically adapted to take advantage of the ability of the power supply/wireless audio distribution assembly 16 to provide them with 12-28 V DC (Class II) electrical power via previously existing speaker wire connections and audio data via wireless Bluetooth transmission. Each of the speakers 18, 20, 102, 104 within the system contains at least one amplifier 18a, 20a, 102a, 104a and at least one Bluetooth receiver 18b, 20b, 102b, 104b. The amplifier 18a, 20a, 102a, 104a of each of the speakers receives electricity from the power supply/wireless audio distribution assembly 16 via the speaker wire 12 and powers the drivers thereof to produce sound in accordance with the audio signals being transmitted (by) from the power supply/wireless audio distribution assembly 16 to the Bluetooth receiver 18b, 20b, 102b, 104b of the speaker 18, 20, 102, 104. The Bluetooth receiver 18b, 20b, 102b, 104b is paired with the Bluetooth transmitters 24 of power supply/wireless audio distribution assembly 16 and receives audio signals instructing the speaker 18, 20, 102, 104 as to the sounds that should be reproduced.
While some speakers within an audio system 10 may be easy to replace with speakers 18, 20 operating in accordance with the present invention (for example, center channel or bookshelf speakers that are positioned on tables, floors or stands within the room), other speakers are more difficult to replace (for example, wall and/or ceiling recessed/mounted speakers). The present invention provides a convenient speaker assembly 100 allowing for replacement of wall and/or ceiling recessed mounted (or surface/bracket mounted) speakers, enabling enhanced sound field reproduction by replacing a single passive-type driver with a plurality of drivers that may be positioned in a variety of orientations, with each array individually selectable for the chosen audio content.
